The file drivers/video/fbdev/auo_k190x.c contains the code: static DEVICE_ATTR(temp, 0644, temp_show, NULL); Is it correct to have the permission 0644 and not have a store function? Should it be 0444 instead? thanks, julia -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
